The study is based on the context of project management; the discipline which employs skills and knowledge to achieve project goals through various project activities. The study concentrates on project management applications to deliver low cost houses (LCH) in the Metsimaholo Local Municipality (MLM). The main purpose of project management application is to enable project managers to track the progress of a project that they are working on. Institutions working on a very large project require project management applications to give periodic updates on the progress of the work that is being done on a project. By using a project management application, the process is made somewhat easier, in the sense that a project manager can just refer and check on the progress him/herself. Provision of adequate housing for the homeless and others who are inadequately housed in an attempt to reduce poverty and improve quality of people’s life has been a huge challenge to the South African government, particularly in the MLM over the years. Globally, legislators on the physical infrastructure of Parliament are pushing for the urgent construction of LCH by the government. The abovementioned challenge has resulted in an enormous housing backlog with poverty, unemployment, economic stagnation and negative behaviour. Financial constrains are seen to escalate costs and this makes the task even more enormous. The hypothesis for this study indicated that MLM does not possess sufficient institutional capacity to implement project management for the effective delivery of low cost housing. The hypothesis and research objectives of the study were validated by means of literature review and empirical surveys. Thirty-four (34) semi structured questionnaires were used to interview participants in the provision of LCH in MLM. The study is made up of five chapters. The study specifically focused on the application of project management to deliver LCH in the Metsimaholo Local Municipality (MLM). •This study contends that the application of project management in the public service sector to deliver goods and services has not been scientifically applied in a conscience and systematic manner. •In the MLM the national, provincial and the municipality efforts are challenged to provide houses for the homeless. •The increasing population in the MLM has resulted in an enormous housing backlog with poverty, unemployment, and economic stagnation. •The high demand for housing in the MLM brings about financial constrains and makes the task even more enormous. •It is realised through this study that the application of project management is lacking; whereby important pillars of project based outputs such as time, quality and cost are not necessarily the resultant finished products of the community tend to inherit. It is evident from the above that while the MLM has a mandate to provide service delivery it is limited by protocol to take full responsibility in the provision of low cost houses. The provision of LCH requires strengthened co-operative governance in the Free State Province, since the three spheres have important roles to play. In the face of the huge backlogs in housing and human settlement provision, the country urgently needs to develop the technical knowledge and skills necessary to fast track housing delivery. / M, Development and Management, Public Management and Administration, North-West University, Vaal Triangle Campus, 2012

Web applications have come a long way both in terms of adoption to provide information and services and in terms of the technologies to develop them. With the emergence of richer and more advanced technologies such as Ajax, web applications have become more interactive, responsive and user friendly. These applications, often called Rich Internet Applications (RIAs) changed the traditional web applications in two primary ways: Dynamic manipulation of client side state and Asynchronous communication with the server. At the same time, such techniques also introduce new challenges. Among these challenges, an important one is the difficulty of automatically crawling these new applications. Crawling is not only important for indexing the contents but also critical to web application assessment such as testing for security vulnerabilities or accessibility. Traditional crawlers are no longer sufficient for these newer technologies and crawling in RIAs is either inexistent or far from perfect. There is a need for an efficient crawler for web applications developed using these new technologies. Further, as more and more enterprises use these new technologies to provide their services, the requirement for a better crawler becomes inevitable. This thesis studies the problems associated with crawling RIAs. Crawling RIAs is fundamentally more difficult than crawling traditional multi-page web applications. The thesis also presents an efficient RIA crawling strategy and compares it with existing methods.

The ideal squirrel cage motor should have a varying rotor resistance; large at standstill, and decreasing as the speed rises. Overseas - designed high impedance rotors try to fulfil these conditions - mostly used are double cage rotors and die cast aluminium rotors. However, in the South African coal-mining industry these rotors recorded high rate failures with heavy financial losses. As a result, the need for an alternative rotor type that was able to comply with basic conditions ignored before appeared on the market: • Higher reliability with extended life expectancy • Lower total ownership costs • Easy re-manufacturing with components available on the market • Specific performance stability at competitive price. Over the years, only two principles were tacitly accepted in designing squirrel cage rotors: 1. For a single cage rotor, in a circumferential direction around the rotor the squirrel cage bars are placed in the same cylindrical shell, with the same shape and same conductivity. 2. For a double cage rotor, the same rule as above applies; however, in the radial direction, the bars have different shapes and typically different conductivities. The Invention is based on a new principle, i.e. "in a circumferential direction around the squirrel cage rotor, squirrel cage bars may have different conductivities and same shapes, or different conductivities and different shapes”. Mixed Conductivity Fabricated Rotors (MCFR) are designed and manufactured based on this new principle, and are able to withstand the harsh South African mining conditions. Since patented, the invention has been materialised in a set of special rotors powering continuous miners of a reputable coal-mining house, which was spending about R5 million annually on replacing specific imported die cast aluminium rotors only. Fully complying with the above-mentioned basic conditions, the patent offers a large variety of technical and economical advantages, increasing mining processes efficiency beyond expectations. The thesis describes the MCFR's design adaptability by altering the rotor design to meet the demands of a specific engineering application as a base line of drives design. The patent is part of the new South African trend of increasing processes efficiency. It offers large possibilities of designing dedicated motors with a positive impact on the South African economy. Some socio-economical advantages are worthy of considerable study: • Being locally manufactured, the MCFR may reduce the country's economical dependence. • Requiring no special expertise, the MCFR can be produced in any quantity and size without excessive investment. • The MCFR offers an alternative option (product interchangeability) on the market as well as sound competition (with export potential). • The patent ensures business sustainability conditions which diffuse financial constraints on motor manufacturers and end-users during the re-capitalisation process (very loaded in South African economic and industrial environment). / Thesis (Ph.D. (Electrical Engineering))--North-West University, Potchefstroom Campus, 2007.

A framework for assessing the key statistical parameters of complex flows in choosing appropriate turbulence prediction methods on a quantitative basis is developed. These parameters characterise flow/modelling matching conditions quantified in this work. Matching conditions are important in classifying complex turbulent flows in order to frame best practice for model predictions to inform computational aerodynamics design optimisation in the context of virtual test beds. In the incompressible low Reynolds number shear flows considered here, the boundaries of the 'conforming domain' within which turbulence models are valid need to be defined, based on basic mechanisms of turbulence, and the statistical parameters. This has led to a new guideline ‘localness map’ for standard model applications. Since the choice of turbulence model depends on the complexity of the flows considered, it is useful if systematic sets of the parameters indicate the type of flow. They are that of residence time, the degree of spatial non-locality, the straining, and the non-Gaussianity, each of which is appropriately normalised. It can be demonstrated that the quantified map, in particular that of localness for the shear flows, provides a firm foundation for evaluating a wider range of Underlying Flow Regimes, including locating the Underlying Flow Regimes on the generalised localness modeling map as a framework for best practice guidelines. This work produces 7 sets of quantitative localness-structural parameters, which are used as baseline sets for grouping the Underlying Flow Regimes, and hence it opens the possibility of having complete modelling maps for Application Challenges to assess the need for zonal modelling.

The container loading problem considered in this thesis is to determine placements of a set of packages within one or multiple shipping containers. Smaller packages are consolidated on pallets prior to being loaded in the shipping containers together with larger packages. There are multiple objectives which may be summarized as fitting all the packages while achieving good stability of the cargo as well as the shipping containers themselves. According to recent literature reviews, previous research in the field have to large extent been neglecting issues relevant in practice. Our real-world application was developed for the industrial company Atlas Copco to be used for sea container shipments at their Distribution Center (DC) in Texas, USA. Hence all applicable practical constraints faced by the DC operators had to be treated properly. A high variety in sizes, weights and other attributes such as stackability among packages added complexity to an already challenging combinatorial problem. Inspired by how the DC operators plan and perform loading manually, the batch concept was developed, which refers to grouping of boxes based on their characteristics and solving subproblems in terms of partial load plans. In each batch, an extensive placement heuristic and a load plan evaluation run iteratively, guided by a Genetic Algorithm (GA). In the placement heuristic, potential placements are evaluated using a scoring function considering aspects of the current situation, such as space utilization, horizontal support and heavier boxes closer to the floor. The scoring function is weighted by coefficients corresponding to the chromosomes of an individual in the GA population. Consequently, the fitness value of an individual in the GA population is the rating of a load plan. The loading optimization software has been tested and successfully implemented at the DC in Texas. The software has been proven capable of generating satisfactory load plans within acceptable computation times, which has resulted in reduced uncertainty and labor usage in the loading process. Analysis using real sea container shipments shows that the GA is able to tune the scoring coefficients to suit the particular problem instance being solved.

Background: The placebo effect and the placebo response is a misunderstood phenomenon and their potential is wildly underestimated. Most people, including health care professionals, consider the placebo effect to be a “make believe” effect which only affects gullible people. It is argued that the nurse is in an unusually advantageous position to observe and facilitate the placebo effect and make use of the benefits for the patients. Observation of said response is made by many authors but there is little to no research on the placebo effect from a nursing standpoint. Some of the research results can however be translated to the nurse profession and used in clinical settings. Aim: The purpose is to describe areas where the placebo effect may affect nursing of the patient. Method: A literature review format was chosen to comprise existing knowledge on the placebo effect, which can be applied for nursing. Results: Themes that arose from examination of chosen literature included: Emotional state, Expectation and Conditioning, Conscious and Social learning and Patient-caregiver relationship. Many of the observed interventions could be applied using the nursing philosophy of Hildegard Peplau. Conclusion: The placebo effect can be used by the nurse to improve the result of the patient´s treatment. If placebo becomes a focus in nursing research the results could be more applicable to benefit patients than if researched by other professional groups.

The primary aim of this dissertation is to examine the hermeneutical foundation, the biblical basis, the historical principle, and then to formulate a four-bridge application paradigm based on four distinguished processes--exegetical, doctrinal, homiletical, and transformational--aiming at transforming the lives of listeners for the glory of God. Chapter 1 analyzes the indispensability of a well-balanced hermeneutical application paradigm by arguing the relationship between hermeneutics and application, by reexamining application paradigms and bridge-building models, and by refocusing the four bridge paradigm. Chapter 2 examines the sermons of biblical prototypes--Moses, Ezra, the Minor Prophets, and Paul--and their features of application paradigms by means of a paradigmatic analyses rather than an exhaustive one. This chapter thoroughly explores Paul's sermons in his epistles, his preaching in Acts, and his hermeneutical bridge-building paradigm. The essential characteristics of these biblical models lead to a four-bridge life-changing application paradigm. Chapter 3 investigates four exemplary historical models--John Chrysostom, John Calvin, Jonathan Edwards, and John Broadus--and examines their illustrative sermons to identify their indispensable principles of application paradigms and to apply these historical facets for formulating a contemporized application paradigm. Four models provide a historical validation to formulate a legitimate life-changing application paradigm. Chapter 4 proposes a four-bridge application paradigm rooted in hermeneutical, biblical prototypes and historical models. The chapter systemizes (1) an exegetical bridge for discerning the aim of author-intended signification and the criteria for transferring universal principles of application (2) a doctrinal bridge for examining seven master keys to unlock the universal principles of ethical application, (3) a homiletical bridge for identifying a variety of relevance categories, legitimate methodologies of audience exegesis and adaptation, and an appropriate degree of transfer, and (4) a Spirit-led transformational bridge that is legitimate to change the lives of listeners. Chapter 5 concludes that contemporary preachers, as bridge-builders, need to seek a life-transforming application paradigm by utilizing the exegetical bridge, the doctrinal bridge, the homiletical bridge and the Spirit-led transformational bridge.

Le laboratoire DOMUS développe des applications pour assister les personnes en perte d'autonomie et les personnes avec des troubles cognitifs. Chaque application est ou a déjà été le sujet de plusieurs études d'utilisabilité qui permettent de les améliorer. Ces études prennent beaucoup de temps à mettre en place, car l'on rencontre souvent des problèmes de logistique (format et sensibilité des données, chercheurs répartis sur une grande aire géographique). C'est pourquoi un outil appelé GEDOPAL a été développé. Il permet de partager entre chercheurs de différents centres les données créées et utilisées lors de la mise en place des études d'utilisabilité. La conception et la réalisation de cet outil ont nécessité une réflexion en amont sur la nature et la sensibilité de ces données. Cette réflexion est l'objet du Chapitre 3. Ces études prennent aussi beaucoup de temps lors de l'analyse des résultats. De plus, certaines données créées lors de ces études, telles que les traces d'utilisation ont des volumétries trop importantes pour être analysées manuellement. C'est pourquoi nous avons créé un processus permettant d'analyser ces traces d'utilisation pour y détecter les erreurs utilisateurs dans l'espoir de les relier à des problèmes d'utilisabilité. Ce processus se compose de deux parties : la première est une analyse formelle de l'application, qui sera présentée au Chapitre 4, et la seconde l'application d'un outil d'apprentissage automatique aux traces d'utilisation pour y détecter les erreurs utilisateurs. Cet outil est présenté au Chapitre 5.
